As we discussed before. Taoism and Confucianism was considered a religion in China. Buddhism first made an appearance in China in 500 BC. Buddhism was at first accepted but latter China started violently repressing the religion. Many peasants found Buddhism attractive because it offered a way out of the hard peasant life.
Christianity, Islam, as well as Judaism also made its way to China. But they were never able to become the dominant religion in China. The traditional Chinese gods, ancestor worship as well as Buddhism remain the most important aspects of Chinese Religion.
